SPOTLIGHT.

. Application filed June 26, 1924. Serial No. 722,435.

To all whom it may concern:

Be it known that I, CLARENCE P. DAVEY, a citizen of the United States,and a resident of Marion, in the county of Grant and State of Indiana,have invented certain new and useful Improvements in Spotlights, ofwhich the following is a full, clear, and exact description.

The invention relates to spot-lights of the ty e adapted to bemanipulated on the outslde of the vehicle from the inside thereof. Itsobject is to provide an improved spotlight of this type which can beeasily installed, is simple in construction and can be easily operatedto project a column of light in substantially all directions.

The invention consists in the several novel features hereinafter setforth and more particularly defined by claims at the conclusion hereof.I

In the drawings: Fig. 1 is a side elevation of a spot-light embodyingthe invention, showing it secured in the lower rail of a Wind-shieldframe, parts being shown in section. Fig. 2 is a vertical longitudinalsection, the lamp being broken away. Fig. 3 is a front elevation, theincandescent lamp and reflector being omitted from its supportingbracket. Fig. 4 is a detail'of one of the clampin plates used insecuring the device to the wind-shield frame. Fig. 5 is a detailperspective of the bearing sleeve which extends through the frame. Fig.6 is a section on line 6-6 of Fg. 2. Fig. 7 is a section on line 7 -7 ofFig. 1.

The invention is exemplified in a lamp comprising a reflector 9 providedwith a marginal flange 10 in which a lens 11 is suit? ably held. A splitring extends around the flange 10 and the margin of the lensto hold thelatter in connected relation to the reflector. The central portion ofthe reflector 9 is provided with a rearwardly extending flange 13 whichis ressed into interlocked relation with a cy indrical sleeve 14. Alamp-socket 14 is secured in said sleeve, and the base of anincandescent lamp 15 is removably held in operative position in thesocket by a pin-and-slot connection 15. Sleeve 14 is held in the tubularportion 17 of a lamp-supporting bracket 17 by means of a set-screwthreaded to the bracket. The rearend of the tubular portion of bracket17 is closed, as at 17". Bracket 17 is preferably formed of a strip'ofsheet metal bent to form the tubular portion 17 and members extendeddownwardly to form an arm 18. A sleeve 36 extends through a hole boredin the lower rail 37 of a wind-shield frame. The front portion of saidsleeve is disposed outside of the vehicle and is there provided with anenlarged portion 45 terminating at its front end in a shoulder 46. Acollar 50 extends and is rotatable around the enlarged portion 45 ofsleeve 36 and is preferably formed of sheet metal bent to form a tubularportion 50 and lugs 50*, which are spaced apart and constitute aforwardly extending arm 51. The lamp-supporting bracket 17 is pivotallysupported by a pivot 52 supported in said arm 51. Clamping plates 38 and39 are elongated laterally and have their ends shaped to conformto thefront and rear faces of the windshield rail 37 and provide additionalbearing surfaces for the sleeve 36. Plate 39 is provided with lugs 40fitting in recesses 41 in the enlarged portion 45 of sleeve 36 to lockthe sleeve against rotation in the wind-shield frame. The sleeve 36 isheld against longitudinal movement by a nut 43 which is screw-threadedto a thread on the rear portion of said sleeve. A look washer 42 isinterposed between said nut and clamping plate 38. Collar 50 fitsbetween clamping plate 39 and shoulder 46 on sleeve 36. A bolt 50extends through lugs 50 to clamp the cylindrical portion 50 with greateror less force of collar 50 around the sleeve to frictionally hold thecollar against rotation with the force desired and to correspondinglyhold the lamp-supporting bracket 17 against such accidental rotation.

A hollow shaft 20 extends longitudinally through sleeve 36 and isslidable therein. The front end of said shaft is provided with a fork 21to which arm 18 is pivotally connected by a pin 22 which passes throughholes in the fork and a curved slot 19 in the lower end of said arm, sothat the lamp-carrying bracket, which is pivotally supported at 52, maybe rocked in the plane of arm 18 or, radially with respect to shaft 20by the longitudinal movement of said shaft. The inner end of sleeve 36is split longitudinally at 36 and screw-threaded, and a nut 44, with atapered female screw-thread fitting the thread 36', is adapted toadjustably compress the split end of sleeve 36- to frictionally hold theshaft 20 against longitudinal movement cin the sleeve. By adjusting nut44, the frictional grip of shaft 20 may be varied to suit the individualusers and to assure the holding of the shaft against movementresultingfrom the vibration of the vehiclc. tation of collar 50 may be varied bythe adjustment of nut 43 for the same urpose.

The inner end of the shaft20 is provided with a handle 2.3, whereby itmay be shifted longitudinally or rotated. The inside of this handle isprovided with a chamber 26, in which is disposed a switch which isadapted to be manually operated from the inslde of the vehicle. Thisswitch comprises a pair of separate spring terminals 28, 29 mounted onan insulating block 27. Contact 29 is connected to the lamp-socket 14 inthe sleeve 14 by a flexible conductor 32 which passes through hollowshaft 20 and through the back of the bracket 17 The other contact 28 isconnected to a conductor 33 which is suitably connected to a battery, aswell understood in the art. A slidable contact button 31 is mounted in acap 30 which closes the rear end of handle 23. This handle is removablysecured .to shaft 20, so that the shaft 20 and sleeve 36 maybe passedthrough the wind-shield before the handle is attached.

The handle is connected to said shaft by means of a stud 24 and aclamping collar 24. The front end of the handle is split, as at 3, so itcan be pressed firmly around said shaft. so its inner end will be heldin a hole 20 in the hollow shaft. This collar is adapted to be clampedaround the handle by a bolt 24. lVhen the collar is removed, the studcan be inserted through the handle and into hole 20" after the shaft 20and sleeve 36 have been passed through the wind-shield frame.

The lamp and its supporting bracket 17 can be adjusted radially of shaft20 by shifting the handle 23 forwardly or backwardly by means of thepivotal and sliding connection 22, 19, the bracket swinging around thepivot 52. The bracket 17 and lamp are bodily and rotatably adjustable bythe rotation of handle 23, this movement being effected through shaft 20which will-rotate the bracket 17 and collar 50 together when the handleis rotated, the collar 50 being rotatable around the sleeve 36. By meansof these two adjustments, the lamp may be universally adjusted toproject a column of light to anydesired point or in any desireddirection within the range for which it is designed.

\Vhen the lamp is to be installed, it is only necessary to drill a holein the wind-shield rail 37 for the sleeve 36. With the handle 23 removedfrom shaft 20 and clamping-plate 38, washer 42 and nuts 43, 44 removedfrom sleeve 36, the latter may be inserted into the wind-shield from thefront thereof, while The frictional retardance to the ro- Said collaralso holds the stud 24' the collar 50, bracket 17 and shaft 20 remain inconnected relation. Next, the clam ing plate 38, washer 42 and nuts43,44 wil be placed in operative osition, whereupon the sleeve will beproper y mounted in the frame. After the sleeve 36 and shaft 20 thereinhave pended claims, without departing from the 80 spirit and scope ofthe invention.
